Abstract
This description relates to a method for suppressing intermodulation distortion in a digital output signal of a radar device. In one implementation, the method includes—in a first mode—feeding a test signal into a receiving channel, the test signal is fed to a mixer contained in the receiving channel and is downconverted to a baseband, a baseband signal that includes intermodulation products on account of a nonlinearity of the transfer characteristic of the receiving channel being provided at the mixer output. The digital output signal is generated based on the baseband signal. The method further includes—in the first mode—determining an intermodulation product and, on the basis thereof, ascertaining a parameter of a model characterizing the nonlinearity. In a second mode, in which an antenna signal is fed to the mixer—suppressing the intermodulation product in the digital output signal based on the parameter and the baseband signal.
